Problems with my new ball

[Seprico]

I just got a 2yr old ball from a friend he is in great health but was handled quite a bit by the previous owner. he is always trying to get out of his cage and now he is being very standoffish with me. if i walk up to his cage he constantly watches me no matter what i do he is looking right at me kinda makes me afraid to handle him not that he could really hurt me but i really dont want to get bit any advice on what i can do or handling tips.
